FULL POWER UPLINK TRANSMISSION ENHANCEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18375965 titled 'FULL POWER UPLINK TRANSMISSION ENHANCEMENT

Simplified Explanation

The abstract describes a method for operating user equipment (UE) in a wireless communication system. Here are the bullet points explaining the patent/innovation:

• User equipment (UE) generates a list of transmit precoding matrix indicators (TPMIs) selected from a set of available TPMIs stored at a base station (BS).
• The UE transmits data indicating the TPMI list to the BS.
• The UE also transmits an index of the TPMI list to the BS.
• The BS sends downlink control information (DCI) to the UE, which includes an indication of at least one TPMI from the TPMI list based on the index.
• The UE uses the indicated TPMI to transmit uplink data to the BS on a physical uplink shared channel (PUSCH).

Potential applications of this technology:

• This method can be applied in various wireless communication systems, such as 4G LTE and 5G networks.
• It can improve the efficiency and reliability of uplink data transmission in wireless communication systems.
• The method can be used in mobile devices, IoT devices, and other wireless communication devices.

Problems solved by this technology:

• The method solves the problem of selecting an appropriate transmit precoding matrix indicator (TPMI) for uplink data transmission.
• It eliminates the need for the base station (BS) to explicitly inform the UE about the TPMIs to be used.
• The method simplifies the process of selecting and using TPMIs, reducing complexity and improving system performance.

Benefits of this technology:

• Improved uplink data transmission efficiency and reliability.
• Reduced complexity in the selection and use of transmit precoding matrix indicators (TPMIs).
• Enhanced overall performance of wireless communication systems.
• Increased capacity and throughput in the uplink channel.

Original Abstract Submitted

A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.
